Product Description

++++General
Vacuum contactor uses vacuum interrupter to extinguish arc to frequently connect and cut off normal working current. It is usually used for 6-40.5kV system AC motor in long distance connection and disconnection.
++++Application
FVC series of Medium voltage vacuum AC contactors are widely used in coal, power, metallurgy and textile. High building and other industry departments. Medium voltage vacuum AC contactor is suitable for communication: 50-60HZ. rated voltage: 7.2kV/12kV/13.8Kv/15kV/24Kv rated current 63 to 630A feed network for long distance connection and Open circuit, and frequent starting and stopping the use of AC motor. It is especially suitable for assembling with all kinds of protective devices to form flameproof electromagnetic starter.
